Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a laser cutting and forming device for camera lenses. Background Technology

[0002] In the field of laser processing, lasers, with their significant advantages such as concentrated energy, high processing precision, and non-contact operation, have become a core technology for material processing. Camera lenses, as key components for optical imaging, have extremely high requirements for processing precision and surface quality. Laser cutting technology, through precise control of the laser beam, can quickly and accurately cut lens materials. Compared with traditional processing methods, it can significantly improve production efficiency and product quality. Therefore, a laser cutting device for camera lenses is particularly needed.

[0003] Chinese patent CN222406091U, published on January 28, 2025, discloses an optical lens cutting device. A first servo motor and a second servo motor operate simultaneously. The first servo motor drives a threaded rod to rotate, causing a second slider to move within a groove in a fixed plate. This, in turn, moves a connecting plate and a sliding rod, causing the electric cutting blade to move laterally. Simultaneously, the second servo motor drives a rotating disk, causing components within the fixed plate to rotate simultaneously. This causes a first sliding plate to move longitudinally on the connecting rod, synchronizing the longitudinal movement of the electric cutting blade. This automated operation allows for faster lens cutting and saves time and costs. However, this optical lens cutting device lacks an effective lens fixing mechanism, leading to lens displacement during actual cutting, resulting in cutting errors and affecting the processing accuracy and yield of the optical lenses. Utility Model Content

[0004] The purpose of this invention is to provide a laser cutting and forming device for camera lenses, in order to solve the problem mentioned in the background art that existing optical lens cutting devices lack an effective lens fixing device, which makes the lens prone to displacement during the actual cutting process, leading to cutting errors and affecting the processing accuracy and yield of optical lenses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a camera lens laser cutting and forming device, comprising a base cabinet, a cabinet door rotatably connected to one side surface of the base cabinet, a worktable fixedly connected to the upper surface of the base cabinet, a housing fixedly connected to the upper surface of the worktable, a first groove and a second groove formed on one side surface of the housing, a sliding track formed on one side surface of the housing, an adjustment mechanism provided on the upper surface of the base cabinet, a connecting arm provided on one side surface of the adjustment mechanism, and a laser cutting machine slidably connected to one side surface of the connecting arm;

[0006] The adjustment mechanism includes a motor, which is fixedly connected to the upper surface of the base cabinet. The motor is rotatably connected to a main shaft. A fixed seat is rotatably connected to one side surface of the main shaft. A track is slidably connected to the outer wall surface of the main shaft.

A gear is fixedly connected to one side surface of the round rod. A support plate is penetrating the round rod. A first rack is meshed with the outer wall surface of the gear. A pressure plate is fixedly connected to one side surface of the first rack. A second rack is meshed with the outer wall surface of the gear. A guide rod is penetrating one side surface of the second rack. A crossbeam is fixedly connected to one side surface of the second rack.

[0007] Preferably, the inner wall dimensions of the first groove and the second groove are the same and are distributed in parallel, and the outer wall dimensions of the connecting arm match the inner wall dimensions of the first groove and the second groove.

[0008] Preferably, the sliding rails are provided in two identical sizes and are symmetrically distributed along the central axis of the outer shell, and the inner wall size of the sliding rails matches the outer wall size of the end of the first rack away from the gear.

[0009] Preferably, the first rack has two of the same size and is symmetrically distributed along the central axis of the round rod, and the second rack has two of the same size and is symmetrically distributed along the central axis of the round rod, with the two first racks and the two second racks being parallel to each other.

[0010] Preferably, the gears are provided in two identical sizes and are symmetrically distributed along the central axis of the round rod, and the central axes of the gears, the round rod, and the rotating shaft coincide.

[0012] Preferably, the guide rods are provided in two identical sizes and are symmetrically distributed along the central axis of the round rod, and the support plates are provided in two identical sizes and are symmetrically distributed along the central axis of the round rod.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This camera lens laser cutting and forming device, through the setting of the adjustment mechanism and the linkage structure of the double rack and gear, realizes the synchronous operation of lens clamping and fixing and laser cutting machine horizontal position adjustment, avoiding the accumulation of errors caused by step-by-step operation, and greatly improving processing accuracy. The motor-driven automated operation mode reduces manual intervention, which not only improves production efficiency but also reduces labor intensity. The "U"-shaped design of the pressure plate can fit tightly with the surface of the camera lens, enhancing the stability of fixing and preventing lens displacement during cutting. The precise limiting of components such as sliding rails and guide rods ensures the smoothness and reliability of the movement of each component, extends the service life of the equipment, and also provides a guarantee for the safety of the cutting process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a camera lens laser cutting and forming device, including a base cabinet 1, a cabinet door 2 rotatably connected to one side surface of the base cabinet 1, a workbench 3 fixedly connected to the upper surface of the base cabinet 1, a housing 4 fixedly connected to the upper surface of the workbench 3, a first groove 5 and a second groove 6 on one side surface of the housing 4, a sliding track 7 on one side surface of the housing 4, an adjustment mechanism 8 on the upper surface of the base cabinet 1, a connecting arm 9 on one side surface of the adjustment mechanism 8, and a laser cutter 10 slidably connected to one side surface of the connecting arm 9;

[0023] The adjustment mechanism 8 includes a motor 801, which is fixedly connected to the upper surface of the base cabinet 1. A main rotating shaft 802 is rotatably connected to the motor 801. A fixed seat 803 is rotatably connected to one side surface of the main rotating shaft 802. A track 804 is slidably connected to the outer wall surface of the main rotating shaft 802. A secondary rotating shaft 805 is slidably connected to the inner wall surface of the track 804. A round rod 806 is penetrated through one side surface of the secondary rotating shaft 805. A gear 807 is fixedly connected to one side surface of the round rod 806. The round rod 806 penetrates through a support plate 808. The outer wall of the gear 807... A first rack 809 is surface-engaged, and a pressure plate 810 is fixedly connected to one side surface of the first rack 809. A second rack 811 is meshed with the outer wall surface of the gear 807. A guide rod 812 is penetrating one side surface of the second rack 811, and a crossbeam 813 is fixedly connected to one side surface of the second rack 811. The system is connected via a motor 801, main shaft 802, fixed seat 803, track 804, driven shaft 805, round rod 806, gear 807, support plate 808, first rack 809, pressure plate 810, second rack 811, and guide rod 812. With the installation of the guide rod 812 and crossbeam 813, during use, the motor 801 starts working, and its output power drives the main shaft 802 to rotate. At the same time, the fixed seat 803 provides support for the main shaft 802. The main shaft 802 transmits power to the driven shaft 805 through the track 804, causing the driven shaft 805 to rotate synchronously. Since the round rod 806 is fixedly connected to the driven shaft 805, the round rod 806 on the support plate 808 also rotates, thereby driving the gear 807 fixed on its surface to rotate. During the rotation, the gear 807 interacts with the first racks 8 on both sides respectively. The first rack 809 and the second rack 811 mesh with each other. As the gear 807 rotates, the two first racks 809 will move in opposite or opposite directions along the surface of the outer shell 4 under the limit of the sliding rail 7. The pressure plate 810 fixed on the first rack 809 will also move accordingly, which can be used to clamp and fix the camera lens placed on the worktable 3. At the same time, the two second racks 811 will move in the opposite direction to the first rack 809 under the guidance of the guide rod 812. This can adapt to different lenses and has strong versatility and flexibility.

[0024] Furthermore, the inner wall dimensions of the first groove 5 and the second groove 6 are the same and are parallel. The outer wall dimension of the connecting arm 9 matches the inner wall dimensions of the first groove 5 and the second groove 6. Through the arrangement of the first groove 5, the second groove 6 and the connecting arm 9, the connecting arm 9 can slide along the inner wall of the first groove 5 and the second groove 6 during use. Since the first groove 5 and the second groove 6 are parallel and have the same inner wall dimensions, and the outer wall dimension of the connecting arm 9 matches them, the connecting arm 9 can slide smoothly in the two grooves, achieving precise guidance and positioning of the mechanism.

[0025] Furthermore, two sliding rails 7 of the same size are provided and symmetrically distributed along the central axis of the outer shell 4. The inner wall size of the sliding rail 7 matches the outer wall size of the end of the first rack 809 away from the gear 807. With the arrangement of the sliding rail 7 and the first rack 809, when the gear 807 rotates and drives the first rack 809 to move along its length direction, the end of the first rack 809 away from the gear 807 will slide in the inner wall of the sliding rail 7. Since there are two sliding rails 7 and they are symmetrically distributed along the central axis of the outer shell 4, and their inner wall size matches the outer wall size of the first rack 809, the two sliding rails 7 can provide stable support and precise guidance for the first rack 809, thereby improving the stability of the mechanism.

[0026] Furthermore, two first racks 809 of the same size are provided and symmetrically distributed along the central axis of the round rod 806. Two second racks 811 of the same size are provided and symmetrically distributed along the central axis of the round rod 806. The two first racks 809 and the two second racks 811 are parallel to each other. With the arrangement of the first racks 809 and the second racks 811, during use, as the gear 807 rotates, the two first racks 809 will move in a straight line relative to or opposite to each other along the surface of the outer shell 4 under the limit of the sliding track 7. The pressure plate 810 fixed on the first racks 809 will also move accordingly, which can be used to clamp and fix the camera lens placed on the worktable 3. At the same time, under the guidance of the guide rod 812, the two second racks 811 will move in a straight line in the opposite direction to the first racks 809, thereby realizing the horizontal position adjustment of the laser cutting machine 10, so that it always maintains a fixed distance from the camera lens.

[0027] Furthermore, two gears 807 of the same size are provided and symmetrically distributed along the central axis of the circular rod 806. The central axes of the gears 807, the circular rod 806, and the rotating shaft 805 coincide. Through the arrangement of the gears 807 and the circular rod 806, when the circular rod 806 drives the gears 807 to rotate, since the two first racks 809 and the two second racks 811 are symmetrically distributed along the central axis of the circular rod 806 and mesh with the gears 807, the rotational motion of the gears 807 will be synchronously converted into the linear motion of the four racks. The symmetrical rack design makes the gears 807 evenly stressed during transmission, effectively avoiding problems such as wear of the gears 807 and shaft misalignment caused by unilateral stress, extending the service life of the transmission components, and improving the reliability of the mechanism operation.

[0028] Furthermore, the outer wall dimensions of the slave shaft 805 and the main shaft 802 are the same and they are parallel. The cross-section of the pressure plate 810 is designed in a U-shape. During use, the motor 801 drives the main shaft 802 to rotate. Since the outer wall dimensions of the slave shaft 805 and the main shaft 802 are the same and they are parallel, the track 804 can fit tightly against the outer walls of both, achieving stable transmission and reducing the failure rate of the mechanism.

[0029] Furthermore, two guide rods 812 of the same size are provided and are symmetrically distributed along the central axis of the circular rod 806. Two support plates 808 of the same size are provided and are symmetrically distributed along the central axis of the circular rod 806. With the guide rods 812 provided, when the gear 807 rotates and drives the second rack 811 to make linear motion, the second rack 811 will slide along the axial direction of the guide rods 812. The guide rods 812 restrict the movement trajectory of the second rack 811, so that it can only make linear motion along the direction of the guide rods 812, effectively avoiding the second rack 811 from deviating or shaking during the movement, and improving the stability of the mechanism.

[0030] Working principle: When the camera lens laser cutting and forming device is started, the motor 801 starts working, and its output power drives the main rotating shaft 802 to rotate. At the same time, the fixed seat 803 provides support for the main rotating shaft 802. The main rotating shaft 802 transmits power to the driven rotating shaft 805 through the track 804, so that the driven rotating shaft 805 rotates synchronously. Since the round rod 806 is fixedly connected to the driven rotating shaft 805, the round rod 806 also rotates, thereby driving the gear 807 fixed on its surface to rotate. During the rotation, the gear 807 meshes with the first rack 809 and the second rack 811 on both sides respectively. As the gear 807 rotates, the two first racks 809 will move in a straight line relative to or away from each other along the surface of the outer shell 4 under the limit of the sliding track 7. The pressure plate 810 fixed on the first rack 809 will also move accordingly, which can be used to press the plate placed on the outer shell 4. The camera lens on the workbench 3 is clamped and fixed. At the same time, the two second racks 811, guided by the guide rod 812, move in a straight line in the opposite direction to the first rack 809, thereby driving the crossbeam 813 to move. One end of the connecting arm 9 is connected to the crossbeam 813, and the other end is slidably connected to the laser cutting machine 10. Since the inner wall dimensions of the first groove 5 and the second groove 6 match the connecting arm 9, and the sliding track 7 is adapted to the first rack 809, when the second rack 811 drives the crossbeam 813 to move, it will cause the connecting arm 9 to slide in the first groove 5 and the second groove 6, thereby realizing the horizontal position adjustment of the laser cutting machine 10, so that it always maintains a fixed distance from the camera lens. The model of the motor 801 is YE2-132S-4. This completes the use process of a camera lens laser cutting and forming device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
